If you receive a 403 error (Invalid Delivery State {0})when pressing a button on a dashboard the button is most likely not detecting a change in dashboard state. To Fix:

  1. If you have multiple buttons, have the buttons "Reload On" eachother.
  2. You should also remove "Assert State: Complete", or your buttons will all disable after one is pressed

gButton1

Reload On: Reload; gButton2

Assert State:

gButton2

Reload On: Reload; gButton1

Assert State:
